IIIIIILIIIIIIIIIII GEORGE MGCREARY PINKERTON, OF YORK, PENNSYLVANIA.

MACHINE FOR VICLDING AND CUTTING ICE-CREAM.

SPECIFICATION forming part of Letters Patent No. 656,044, dated August 14, 1900.

Application fled March 22, 1900. Serial No. ,764. (No model.)

PINKERTON, residing at York, in the county ofV York and State of Pennsylvania, have invented certain new and useful Improvements inA IWIachines for Molding and Cutting Ice-Cream,

of which the following is a specification.

This invention has for its object a machine for molding and cutting ice-cream, of a very simple and economical construction, whichv can be easily manipulated-.aud which will effectively serve for its intended purposes.

The invention consists in the novel features' of construction and combination of parts, which I' shall now proceed to describe and claim, reference being had to the accompanying drawings, in which-- Figure 1 'is a front perspective view of the improvement. Fig. 2 is a longitudinal section of the front or cutter end. Fig. 3 is a detail view of the pawl devices hereinafter referred to, and Fig. I is a detail .view of the means for tilting the Slicer-knife.

My improvement comprises a suit-able frame having a longitudinal-'bed portion 1, on the frontend of which ismounteda suitable vertical frame 2, in vwhich the mold is adapted to be secured.

3 3 indicate two guide-rods in front vertically movable on thefrarne 2, to which is secured a cross wire or blade knife 4,.adjusted by means of tension-bolts 5 5.

6 6 indicate a pair of guide-posts fixedly held between the guide-rods 3 3, on which is supported a slicing-knife 7, having a rockerbearing, one end thereof connecting with a crank 7a, said knife being adapted to tilt the cream off onto the wrappers 8, disposed on the table 9 in front of the discharge end of the machine, as clearly shown in Fig. 1. After having been tilted the Slicer-knife is returned to its normal (slicing) position by means of a stay 11 and the coiled spring 12, which draws it against the stay.

The guiderods 3 3 have a cross-head 3a at the top, centrally of which projects a vertical guide or extension 10, having a fixed inwardly-projecting lug 10a at the top and an adjustable lug 10" at the bottom. The lower ends of the vertically-sliding guide-rods 3 3 have a cross-bar 3", with which connects a pendent pitman-rod 3c, pivotally connected atY the lower end to a treadle 13 in such manner that when-the'same is depressed the slidelrods and their. attached cutting-knife will be movedupward in to a position to sever the cream-body into its proper length.

In order to automatically tilt the slicerknife 7, I'pivotallymonnt on a short post adjacent the crank 7a a trip-lever 7", whose weight is so disposed that its forward arm will normally rest loosely on the crank 7 and whose rear arm is in the path of one of the tension-bolts. Thus it will be seen that when the guide-rods. 3 3 move upwardly a bolt 5 will strike against the trip-lever 7b and cause it to depress the crank 7a and tilt the Slicer-knife 7, the latter being returned to normal position by the spring 12, as described above.

In connection with the cutting and slicing means I employ automatically-operated devices for feeding the cream-block forward. In the drawings I have shown the front frame provided with a bifurcated standard 11b, in which is journaled. a bell-crank lever, the long arm 14 of which projects in the path of the lugs IOa 10b of the sliding frame, while its short arm connects with a. pitman 14 to operate the feed-pawls, `presently more fully described. In practice," the lower lug 10b engages the lever-armv let'when the cutterknife is above theA mold. and rocks the lever to eect a feed movementto push the frozen cream-block forward the. desired distance. When pressure on treadle is removed, the guide-rods drop, the knife cutting the cream at suoli movement, and' during this movement the upper lug 10El engages the lever-arm 14 and draws the shifting-pawls back to their rearward (normal) position.

16 indicates the feed or'shifting pawls, of which I preferably employ five and which are held for longitudinal' play, they having slide-block bea-rings 16a, which are adapted to be moved back and forth between the setscrews 19a on the cross-head guide 19, such pawls in practice having theicouter ends terminating in quarter-inch rack-engaging teeth. By adjusting the kset-screws 19, and consequently the movement of thebearingblocks, the thickness of 'the block to be cut is regulated.

20 indicates a combined rack and plunger,

one end of which enters the mold fixedly held at the front end and to which is bolted a wooden block 21, which tits the said mold. The plunger slides on the parallel guideplates 22, secured to the bed-plate 1, and the cross-head guide is also bolted to I[he said bed-plate 1.

From the foregoing description it will be observed that I have provided a very simple and effective means for molding and cutting ice-cream in small blocks to be wrapped in paper, said machine being of such a nature that the blocks can be so quickly and economically cut and wrapped that they can be sold at a very small cost.

It will be understood that by providing a plurality of fxedly-held knives at the front the frozen block can be cut into a number of cakes at each operation of the cuttingknife.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a machine for the purpose specified, the combination with a longitudinal bed, a mold, and a slidable plunger, of the vertical parallel guide-rods, 3, 4, a transverse blade connecting the latter, a cross-head arranged on and connecting the upper ends of said guide-rods, a vertical extension of said crossbar, automaticaily-operated means connecting such extension with the plunger, and a treadle for reciprocating the aforesaid guiderods, substantially as shown and described.

2. In a machine as described, a stationary slicerknife havinga tilting movement, means forautomatically tilting said knife and means for returning it to its normal or slicing position, substantially as shown and described.

3. In a machine as described, a plunger, a bell-crank lever, longitudinally-movable pawls for shifting the plunger forward, the pitman connecting the bell-crank lever and such pawls, and means for manipulating the bell-.crank lever, as set forth. ,A

4. A machine for cutting ice-cream, comprising a suitable framework, a tilting slicing-knife, a reciprocating guide-frame a cutting-knife carried thereby, a plunger meehanism,feedpawls for forcing it intermittently forward and a mechanism for operating said pawls connected with the reciprocating guideframe as set forth.

5. In a machine of the character described, the combination of a vertically-reciprocating cutting-knife, a tiltingslicer-knife, means for operating said cutting-knife, and a trip for tilting said Slicer-knife, said trip being actuated by the operating means for the cuttingknife, as set forth.

6. In a machine of the character described, a reciprocating cutter-knife, guide-rods carrying said knife,a tilting Slicer-knife provided with a crank, and a trip-lever adapted to depress said crank and arranged for engagement by a device carried by one of said guiderods, as set forth.

7. In a device of the character described, a reciprocating cutting-knife, guide-rods carrying said knife, a tilting Slicer-knife havinga crank, a trip-lever adapted to move said crank and arranged to be tripped by the movement of the guide-rods, and spring secured to said crank whereby to return the Slicer-knife to its normal position, as set forth.

8. In a machine of the character described, a mold-box, a cutting-knife movable across said mold-box, guide-rods carrying said knife and having an extension formed with lugs, a bell-crank lever one arm of which is located in the path of said lugs, pawls adapted to feed the material into the mold-box, and a pitman connecting said pawls with the other arm of said lever, as set forth.

9. In a machine of the character described, a mold-box, a plunger and rack-bar adapted to feed the material into said mold-box, pawls arranged for engagement with the rack-bar to feed the same forward, bearing-blocks on which said pawls are moun ted,gnides in which said blocks are slidably fitted, and means in said guides for regulating the movement of said blocks, as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
